My invention relates to certain improvements in locomotive boilersupports, and this application is a companion application to that filedby Henry K. Harwich on November 9, 1929, under Serial No. 405,9911.

The obj ect of the present invention is to re inforce the frame of thelocomotive by a boiler support which extends above the frame and is anintegral part of the frame, and to provide saddles which are secured' tothe scribed in detail hereinafter.

boiler and which are arranged to slide upon the boiler support.

The invention also relates to certain details of construction of thesaddles as de- In the accompanying drawings: Fig. 1 is a side view ofsufficient to a frame of a locomotive showing the boiler support and thesaddles detached from the boiler,

the outline of the boiler being shown in dotted lines;

Fig. 2 is a plan view;

Fig. 3 is a transverse sectional view on the line 3-3, Fig. 1;

Fig. i is an enlarged sectional view on the` line 1r-4, Fig. 1; and

Fig. 5 is a detailed view showing one of the pads on the flange of alongitudinal web. Referring to the drawings, 1 1 are the side 3f framesof a locomotive, having the usual pedestals 2 which are cast integralwith the side frames. Transverse members 3 tie the two side framestogether at intervals. The entire structure is made as an integral cast-I ing but it will be understood, however, that stance, consists of twolongitudinal webs 9` and transverse members a. These transverse membersare arranged at intervals through- A5 out the length of the frame andhave laterally eXtending webs 4a extending from the longitudinal webs 9to points on the main frame, so as to reinforce the web 9 and to ina-yterially increase the strength ofthe entire structure. By extending theboiler support Y construction of the entire frame. At the upp pad whichis located betweenthe -iianges 6 ofv a considerable distance above themain frame, the vertical depth of theframe is iincreased andvstrengthened and the depth 'over the pedestalsis increased, Jermitting.a'lighter per, edge'of each longitudinal web 9 is a flange Y l 10 andat intervalsthis flange Vis'enlarged to form raised pads 11 V(Figs.and-5). The flanges 10 materially strengthen the longitudinal webs andconnect the several pads which carry the boiler. l 'yA l rlhesesegmental flanges 6 of the saddles are secured tothe boiler a by rivetsor studs, or'- theymay be welded thereto if desired. 7 is a` Figi-3.

Each saddle is made as lshown in Figs. 3 and. fi and has' ay portion12which is directly above the upper surface'of the pad 11, and betweenthis padv 11 and the portion 12 ofthe saddle 5 is a gib 13, whichprovides Ia renewable wearing surface and also facilitates fin-v ishingin-this shop as this gibis applied after the saddle is attached to theboiler.Y These gibs ,have lips'at Vboth ends-toretain theniin place andare held transversely of the -locomotive by tap bolts le in the present?instance. Eachsaddle has' a dependingpon tion 15y which is opposite theedge ofthe pad 11, and betweenthis extension and the. edge "of the padis av gib M16, having lips at each end "for retaining it in position onthe saddle and this gib provides' a renewable y wearing`- surface. y y.I

- A cap vplate 17 issecured bypa stud bolt 18 the saddles 5 and theboiler as shown 'in to the underside of the extensionl of the.

'1n the present instance, I have shown 3 saddles "on each side of the`boiler support of the locomotive and these saddles are secured to ytheboiler in the manner shown and are `free to move longitudinally with theboiler on the boiler. support, to allow for expansion and contraction.This boiler support, as

. 00 stated above, 1s, 1n the present instance, an

integral part of the main frame of the locomotive.

1. The combination in a locomotive, of a main frame; a boiler supportthereon projecting above the forward frame and oonsisting of twolongitudinal webs spaced apart; pads on the webs; and saddles on theboiler arranged to slide on the pads of the boiler support. A l

2. The combinationy in a locomotive, of a4 main frame; a boilersupportextending. above the main frame having Va longitudinal flange;pads arranged atintervals o-n the l5 flange; and saddles arranged to besecured tova boiler and to slide on the pads.

3. The combination in a. locomotive, of a main frame integral boilersupports extending above the mainframe, the support consisting oflongitudinal webs and transverse members connecting the iwebs, Leachlongitudinal web having a flange at its upper end;

and a series-of saddles arranged to be secured tothev boiler, saidsaddles being located directly above the flanges of the webs and havingcap plates extending underthe webs.
